This invention relates to hand operated bulletin printing machines ordevices for printing advertising and other matter,

though it is noted that the invention 1sl proved type wheel and carriagecontrol and type spacing mechanism.

Another object of the invention is to provide an apparatus or'v deviceof this kind having improved type alining mechanism.

Other objects 4of the invention are to improve generally the simplicity,speed and efficiency of such devices and to provide a device orapparatus of this kind which is durable, economical to manufacture andoperate, and which will notget out of order.

The inventive features for the accomplish- .ment of these and otherobjects vare herein shown in connection with an improved bulletinprinting machine which, briefly stated, comprises a mainframe carrying asupply roll, a platen bar, and supporting rollers carrying a take-uproll loosely supported on the supporting rollers. Other rollers guidethe paper from the supply roll to and from the platen and thence to thetakeup roll. A carriage pivotal and slidable on a rail carried on theJframe in turn carries a type wheel, and an index wheel operativelyconnected tothe type wheel. A handle extending from the carriage servesto rock the carriage and vpress the type to the paper, and at the sametime actuate a pair of escapement teeth mounted o'n the carriage intocooperation'with a series of rollers mounted on a spacing bar to`advance the carriage. A ratchet on one of the supporting rollers isengaged by a/feed p'awl on a, line spacing lever for feeding the paper;while a detent pawl prevents retrograde motion of the ratchet, and astop pawlprevents overv feed.

Other objects of the invention will appeal' as the description proceeds;and while hereinI details cf .the invention are described,

the invention is not limite-d to these, since manya-nd various changesmay be made without departing from the scope of the invention asclaimed.

In the accompanying drawing, showing by way of example, one of manyVpossible embodiments of the invention,

The operative parts of my improved machine are carried'on a mainframecomprising a pair of end members 10 formed with widely separated feet 11and a cross piece 12 slightly above the middle part, and provided withopen bearing recesses 13 receiving a shaft 14 carrying a supply roll otpaper 15, pressed upon by a resistance roller 16 journalled in the endsof -links 17 pivoted to the frame, to prevent overthrow of the roll.`The paper passes over and under intermediate and lower paper guide`rollers 20` and 21 (Figs 2 and 3) by which paper is guided to and fromthe platen bar 22.

Uprights 23 on the top of the endmembers carry' a top roller 25receiving paper from the lower roller'21 to form a display field 26(Fig. 1). A pair of parallel sup-v porting rollers 27 and 28 (Fig. 2)are mounted at the upper part of the frame to the rear of, said field.The paper passesfrom the top roller under these rollers 27 and 28 to thetake-up roll 29 which is merely loosely supported on the supportingrollers.`

on rail 31 mounted betweenI said members 10 above and to the rear of theplaten carries a carriage frame34 fast on said sleeve A and comprisingrspaced frame members 35 and 36 (Fig. 5) in which is mounted ahorizontalshaft 37 carrying atype wheel e5 'i A sleeve30 (Fig. 3)pivotal and slidable said pinion, and-also carries an index wheel 47 onthe .spindle provided with indicating letters and characters 48acorresponding to the type 39. A pointer 48 is carriedon the saidcarriage frame and disposed over` said indicating wheel, for selectingthe type to,

be rinted. j

handle 50 extending. from the carriage frame serves for rocking the typeto the platen as in Fig. 4. A forward extension 51 4of said carriageframe comprises an ,upper member 52 and a lower member 58, to whichlatter is pivoted an inking roller casing 55 carrying therein an inkingroller 56 pressing against the type. restoring elbow lever 58 pivoted'at its elbow part to /the carriage frame has a lon arm 59, Fig. 3;provided with an end rol er 60 bearing against a .spacing bar 6l. Aspring 63 tensioned between said casing 55 and the short arm of therestoringf lever holdsthe ink roller 56 pressed againstthe type and.said end roller 60 pressed against the spac ing or escapement bar 61thereby to move the type wheel from the platen after printing has beeneffected. An alining pawl 65 pivoted on the carriage frame is acted.upon

y a spring 66 tensioned between a pin 68 on the pawland said -short arm,yw ereby the pawl is caused to engage between the teeth of the ,aliningwheel 41 as the type is pressed a ainst the paper, thereby to alinel thetype. detent finger 67 carried onfsaid elbow lever engages the in 68when the type Wheel is retracted, to li t the pawl from the f teeth .'topermit the type wheel to turn to select another character.

A series of rollers 70 (Figs. 6 and 7) mounted on said spacin bar 61cooperate with a pair of relative y offset inwardly pointed type spacingteeth 71 and 72 mounted on the lower face of said upper member 52 andlsnugly disposable .between said p,

Said teeth have parallel advance rollers. and rear pos1t1omng faces 73and 74 enaging the rollers, and beveled cam faces 6 and 77 engageablewith 'the rollers re" spectively to advance the carriage a half spaceduring the forward stroke, and a half space during the back stroke ofthe type wheel. The forward end 77 of the tooth 71 is pointed for theeasy insertion of the tooth between the rollers when the carriage isoscillated from the position of Fig. 3 to that of Fig. 4. In theposition of Fig. 8, the carriage ma be easily slid toward either end ofthe rail or wide spacing, paragraph` ing or display work.

A line spacing paper feed ratchet 78 (Fig. 8) fast on the rearsupportingl roller 27 has abrupt teeth 79 engaged by a feed pawl 8() ona line spacing lever 81 loosely mounted on the journal of said rearroller.

A spring 83 compressed between vthe tail ofsaid pawl and a socket 84 ofthe lever yieldably holds the pawl in engagement with the teeth. Adetent pawl 85 pivo'ted4v on the main frame lprevents retrograde motionof the roller; While a stop pawl 86 engaging the advance faces of theteeth for preventing over feed, is providedwith a tail 88 engageable bya lifting finger 89 on the lever to hold the stop pawl disengaged fromthe ratchet as the feed pawl moves lto its most retracted position (Fi8) and advances the ratchet a short distance, whereupon the finger 89releases the stop pawl for engagement with the crown of the tooth readyto engage and stop the next tooth when the paper has been fed one linespace, as in Fig. 9. j-

The operation of the devices very simple, and obvious from theforegoing.

- The supply roll 15 is put in place, the paper threaded up'as in Fig. 2and started on the take-up roll 29. The carriage is then slid laterallyyto near the point where the first letter is to bewheel rotated by hanthus inking the type rinted and the index 'until the character to beprinted is opposite 48. The handle 50 is then forced down by hand, thusforcin the pointed end 77 (Fig. 6) between the ro 1ers 70. Continueddownward movement of the handle carries the tooth 71 past the rollersand brings the camV face 77 into camming engagement with the roller 70,moving the carriage a half space just before the type is pressed to thepaper. This movement brings the alining wheel 4l into engagement withthe pawl 65, thus slightly rotating the type wheel, if necessary,

and ahningthe type accurately.

rllhe handle 50 is then released, and on the return stroke, the'cam face76 is brought intocamming engagement with ,a spacing roller, thusspacing the carriage another half letter-space. rl`he above operation isrepeated until a Word is spelled rlhe space between the Words isobtained either by sliding the carriage to the right withoutoscillatingv it, or by repeating the above described operation, exceptthat the type is not brought into contact with the paper. f

After'the line is completed, the paper is fed a line space for the nextline merely `by drawing the lever 81 toward thefoperator to the'positionof Fig. 9, whereupon the end members; a platen thereon; a rail shaftmounted between said vend members above and to the rear of the platen; asleeve pivotal and ,slidable on said shaft; a carriage frame fasten saidsleeve and comprising spaced frame members one of which has upwardlyradially alined bearings a horizontal shaft mounted in the mid part ofthe frame; a type wheel on said shaft provided with peripheral type, andcomprising a bevel pinion; a spindle in the radial bearings; a bevelgear on said spindle engaging said pinion; an indicator wheel on thespindle provided with indicating letters and characters corresponding tothose of the type wheel; a pointer carried on. the said carriage frameand disposed over said indicating wheel; ahandle extending from thelcarriage frame for rocking the type to the platen; and spacing means toadvance /the carriage.
